     \G (double quote). At run-time, return the length, @i{u}, and the
     \G start address, @i{c-addr} of the string. Interpretation: parse
     \G the string as before, and return @i{c-addr}, @i{u}. The
     \G string is stored in a temporary buffer which may be overwritten
     \G by subsequent uses of @code{S"}.

     \G Compilation: Parse a string @i{ccc} delimited by a " (double
     \G quote). At run-time, display the string. Interpretation semantics
     \G for this word are undefined in ANS Forth. Gforth's interpretation
     \G semantics are to display the string. This is the simplest way to
     \G display a string from within a definition; see examples below.
